MV Induction Motors
GEPower Conversion
Experience MattersFor over 100 years, GE has produced countless medium voltage induction machines for the petrochemical, power generation, mining and minerals, water and wastewater industries. These motors are commonly used for centrifugal compressors, blowers, boiler feed pumps, crushers and grinders, multi-stage high pressure pumps such as water injection or pipeline applications.
StandardsGE motors are designed for, but are not limited to these critical industry standards:NEMA MG1IEC 60034-1ANSI C50.41IEEE 112API 541 & 547Applicable ISO, AFBMA, ANSI, ASME, and ASTM requirements
QualityOur world-class testing facility has the capability of meeting a wide range of NEMA, IEC and API motor requirements. GE is dedicated to manufacturing excellence. Our facilities are ISO 9001 Certified with over 20 years of Six Sigma process enhancements and best practice implementations. Our commitment is to deliver the highest quality design to fit your system requirements with service to exceed your expectations.
Reduction of ResonancesGE supplies both flexible and rigid rotor technology. All
machines 1800 rpm and below have rigid rotors as defined
by API. Use of the latest engineering simulation tools and
modern modal testing equipment makes it possible for GE
to assure shaft resonances do not impede operation of the
machine in the specified speed range.
Superior DesignMeets or exceeds API 541 requirements for Petroleum & Chemical ApplicationsGE provides machines that are fully compliant to API 541
standards, globally recognized among the most stringent.
You can be assured that you are getting a well-designed and
reliable product, optimized for your specific application.
Inverter DutyThe insulation system meets the requirements of NEMA MG-1,
part 31. If required, a shaft grounding device is installed to
reduce shaft voltage. Both bearings are insulated and the
drive end bearing is grounded. Our cage induction motors are
certified for use with the GE MV4, MV6 and MV7000 range of
variable frequency drives.
Stator frames are designed using powerful FEA tools. The design tools confirm safety margins, and assure resonances are well outside the operating region.
Improved ventilation and cooling has been achieved with a new internal fan design.
Rotor ConstructionThe magnetic circuit consists of punched thin steel disks
assembled to form a laminated core mounted on the shaft. The
laminations are coated with a temperature stable insulating
film to reduce magnetic losses yet maintain dimensional
stability in the face of severe thermal and mechanical stresses.
The rotor winding consists of a number of uninsulated metal
bars in the outer surface of the magnetic core parallel to the
shaft and short circuited by metal rings at both ends.
BearingsGE uses self-aligning spherical seat sleeve bearings per DIN
31693/4. Seal additions are also available to meet IP-56
requirements. Anti-friction bearings are available with
grease in a sealed housing to avoid contamination meeting
IP56 protection.
Built for DurabilityStator ConstructionLaminations are precision punched from high quality, low loss
electrical sheet steel with a temperature stable insulating film.
The magnetic core consists of ring laminations compressed
and completely wound before the core package is inserted
into the frame.
Insulation SystemGE uses an epoxy solventless resin vacuum-pressure-im-
pregnation (VPI) process assuring long life. For line voltages
of 5000 Volts and above, a semi-conducting armor is applied
to the slot portion and beyond the core to provide corona
protection. The binding agent is GE’s third generation epoxy
resin, selected and tested to IEEE-1776. The coils receive a
protective armor of heavy glass tape for protection against
mechanical shock and abrasion. Custom Polyseal® is a sealed
winding insulation system that meets the requirements of
NEMA MG1 20.18..
It is available upon
request to operate in
severe environments
containing moisture,
oil, chemicals and
salt water.
The stator assembly is configured for increased air flow which improves heat transfer and provides a more compact design.
Self-aligning spherical seat sleeve bearings have features designed to keep the oil in and the dirt out.
Copper bars are brazed to their endrings, and aluminum bars are welded to their endrings.

VerticalAccurate Frequency Response Design System resonance can shorten the life of your equipment.
GE invested in the development and calibration of a new
Reed Critical Frequency (RCF) prediction tool. It arms our
engineers with the accurate data they need to create custom
designs for specific application challenges.
Frame Design - BenefitsLarge inspection windows on both ends of the frame ensure
easy maintenance and inspection access. The modular frame
design accommodates multiple cooling, bearing loading and
protection options without changing
the motor stator frame.
Rotor DesignShaft FEA modeling (including Torsional, Radial and Axial
loads) help ensure rotor designs meet specifed application
requirements.
Bearing DesignAPI compliant options are available for the rolling
element and sleeve bearing
Wound RotorEnergy Recovery SystemGE wound rotor induction motors are designed to operate
with Slip Energy Recovery drives within a standard range of
80% to 110% of the rated speed. Every design is optimized
to suit each application and to provide maximum energy
savings, effective speed control, and high reliability.
Rotor Construction
The rotor has a three-phase insulated winding. Rotor winding
terminals are brought out through rotating slip rings and
stationery brushes. These terminals are used to connect
an external resistor in series with the rotor winding
in order to control the motor accelerating torque and
associated current.
Brush Lifting Device In a traditional application as the motor achieves nominal
speed, the starting resistor is shorted out through the brushes
between the slip rings. This shortens the life of the brushes
and adds extra wear in the motor. An optional solution from
GE, called a Brush Lifting Device, is an integrated mechanism,
which shorts the slip rings and lifts the brushes at nominal
speed to avoid this wear.
